DEVICE FOR PURIFYING FEED-WATER.

SPECIFICATION forming part of Letters Patent No. 503,209, dated August15, 1893. Application filed January 26, 1891. Serial No. 379,19 (Nomodel.)

T0 at whom it may concern:

Be it known that we, JOHN J. HOPPES and EDWARD O. GWYN, citizens of theUnited States, residing at Springfield, in the county of Clark and Stateof Ohio, have invented certain new and useful Improvementsin Devices forPurifying Feed-Water, of which the following is a specification.

Our invention relates to purifying feed-water for steam-boilers andespecially relates to that class of purifiers known as live steampurifiers in which the purifier proper is connected directly to theboiler or boilers so as to receive the full pressure of steam in saidboilers and be subjected to the same or substantially the same conditionas the water in the boilers.

The object of our invention is to provide means for positively feedingsaid purifiers and positively discharging the same into the boilers. Weobtain these objects by the constructions shown in the accompanyingdrawing which is a perspective view illustrating means for obtainingsaid objects.

In the said drawing A A represents the boilers and B, the purifier.

C is a steam-pipe which connects the boilers to the purifier.

It has been common heretofore to place the purifier B, at some pointabove the boilers so that the water forced into the purifierby afeedpumpor other well known means, would feed by gravity from said purifier intothe boiler or boilers; the pressure-being substantially the same in thepurifier and boilers. By the use of our improved devices the purifier B,may be placed in any desired position, either above or below the waterline in the boilers. In the drawing it is shown arranged on the floor ofthe boiler room. I 1

The water is fed-to the purifier in the ordinary way under pressurepreferably by means of a steam pump boiler feeder, and in order that thefeed water may be positively discharged from said purifier and into theboiler we employ a double pump or two pumps operated simultaneously bythe same motive power. This double pump is illustrated at D, in thedrawing; the pump cylindersE and E being connected to and operated froma common steam cylinder E F is an exhaust steam heater through which theexhaust steam from the pump is adapted to pass; the feed water beingpreferably passed through the exhaust heat-er before it is forced intothe purifier. This construction, however, forms no part of our inventionand may or may not be employed, as desired.

We preferably operate the pump D, by steam drawn through a suitable pipea, from the purifier, so as to create a circulation through saidpurifier, and to remove all the air or gases therefrom; abranch pipe at,and suitable valves in said pipes being preferably provided so that thesteam may be taken d rectly from the boiler in case the purifier 1scut-off for cleaning or otherwise. a represents the exhaust steam pipefrom the pump which passes through the heater F, as before described.The water to supply the purifier enters through a pipe I), from anysuitable source of supply, and passes through the heater F, when aheater is employed. Otherwise it is drawn directly from the source ofsupply. It enters the pump cylinder E, as the pump is operated, and isforced through the pipe 2), into the purifier. From the purifier thewater is passed through a pipe 0, to the pump cylinder E, and thencethrough the pipe 0, to the boilers, by the action of the pump.

To provide for feeding the boilers 1n case the purifier is disconnectedfor cleaning or otherwise, we preferably connect the pipes b.

and c, as shown at e, and provide a suitable valve therein so that thewater may be drawn direct from the source of supply into the pumpcylinder E ,and forced directly into the boiler. We also preferablyconnect the pipes c and b, by a branch 6'; suitable valves beingprovided whereby both pump cylinders may be caused to discharge throughthe discharge pipe 0', into the boiler, if desired; this beingpreferably accomplished by the use of a three-way valve e arranged inthe pipe I), so that a communication may be established from the pump E,through the branch e, while the pipe b, is cut-off, or vice versa.Suitable valves are preferably provided in all of the pipes so that eachor any may be cut-01f or a communication established therein, asdesired.

It will be seen that by this construction means are provided whereby adefinite quantlty of water is forced into the purifier by the action ofthe pump at the same time a similar quantity is discharged therefrom,thus furnishing a positive feed for the boilers as well as a positivefeed for the purifier and preventing any unusual accumulation of waterin the purifier.

By the connections, as described, it will be seen that either .or bothpumps may be shut otf, as desired, and one or both be operated to pumpwater directly into the boiler.

It is evident that the special form or construction of purifier, pump orboiler has nothmg to do with the invention, as these may be modified, asdesired, to accomplish the result.

Instead of having the pumping cylinders side by side, as indicated inthe drawing, and connected to the same steam cylinder, the steamcylinder may be arranged in the center with the pump cylinders at eachend, or? they may be otherwise arranged without departing from thespirit of our invention.

Having thus described our invention, we claim- 1. The combination with asteam boiler and a purifierconnected directly thereto, of a pump forsupplying said purifier, and a simultaneously operated pump fordischarging water from said purifierinto the boiler, and a branchconnection between the supply pipes of the respective pumps, andsuitable supply-valves in said branch connection, substantially asspecified.

2. The combination with the steam boilers and a purifier connecteddirectly thereto, of two simultaneously operated pumps adapted todischarge respectively into the purifier and into the boilers, thesupply-pipe of one of said pumps being connected to the purifier andprovided with abranch connection to the supply-pipe of the other pump,and a branch connection with suitable stop-valves between the dischargepipes of the respective pumps, substautially as specified.

In testimony whereof we have hereunto set our hands this 22d day ofJanuary, A. D. 1891.
